iViewer, Android 4.2.1 and multi-user = Licence trouble

[parinacota]

I am testing iViewer #107 (up to this morning) on a Nexus 7 with Android 4.2.1 (the winner version!), in a multi-user environment (2 different account on the same host).

Few remarks:

• Application version is shared between accounts (just update with one account), even if I had to install the application first time under each account
• Configuration file is not shared --> If you want to have the same application on both account, you have to upload-it on both side
• Licence (a list beta one) is not shared... I registered the iViewer app through the beta licence process, used a GUI file with sub panels... and they are only usable on the account where I started the licence process. On the other account, I have "Unregistered Device. The loaded GUI does not contain... Page flips and sub-pages are disabled". I checked: when downloading the GUI file, guiDesigner shows 2 different Device ID, so the explication may be there: the Device ID is "user-account-dependant".
• Network connections are (of course) not merged... so for a Global Cache GC100 for instance (but same thing for my Denon Amp) that only accept 1 concurrent TCP connection, the "2" remotes cannot run concurrently
  • you have to either use non persistent connexion (but not a good idea, as the appliances tcp servers are very weak, I had to reboot my Amp several times, and performances are lower)
  • I wrote a small C "TCP multiplexer" that runs on a small (and old) XP server, that accept many TCP connection but create only 1 connexion to the destination (without a "real" multiplex, all responses are sent to all clients, as I didn't try to understand which response is for which client). Very usefull indeed because now my wife can use its iPad in // as a remote.

==> So only 1 "bug" (but maybe not one): Licence ID is apparently not shared on the same host. ==> I think taht multi-user panel is (for me, so may be for many others) quite important: I like to use my Nexus to read email/manage my Hifi/... but I want a account without my personal activities when somebody else use it as a "remote" (as the babysitter).

Other elements (install, config file, ...) are maybe just "normal", I didn't find so much literature about how Android 4.2 manage the multi-user in details.
